'Wrong way' sign can fool drivers going the right way

I remember as a young driver seeing the bright-red "Wrong way" sign for the first time. It struck panic throughout my entire body, and I slowed down until I was certain I had entered the freeway properly. It turned out to be one of many wrong-way signs along Arizona freeways that are visible to both right-way and wrong-way drivers.

Over the years, after seeing the formerly panic-inducing wrong-way signs dozens of times while driving on the right side of the road, I became desensitized to them. It's my fear that true wrong-way drivers may see those signs but ignore them because they hold little novelty for the experienced Arizona driver.

Perhaps a change in sign design to something unlike any other road signs, as well as the proper placement and angling of the signs, would elicit the "panic-inducing" moment we hope might prevent the next accident. Whatever the solution is, I hope we can avoid our tendency to overspend and underthink about addressing issues such as these.
